i use it. why do i use it? when i put in a search term, thanks to collaboration, wikipedia is the first hit. it needs to be. nowadays. i look at it first hit gives me ideas and says this is what i have to do research on. the question is of any kind of research, do you stop fair? to use a done deal? or do you say have learned some rain, but now i need to go learn it in depth. the problem is that lack of in-depth learning and the lack of motivation. the lack of saying i could actually read a book. so many libraries to get rid of the book and say what you need to do is treated as an e-book for some kind of a file. the problem with that is we lose the contemplation. we lose the hands on the plane out five books and saying this was his face. his son says something very different. what do i know about the authors? this is what we used to train students to do. the technology is not hot enough that kind of teaching, which is to her students -- are meant in our society's detriment. >> host: naomi baron, who was studying
